Configuring libjpeg

Configuration Information

As with most libraries, there is no configuration to do, save
that the library directory, i.e., /opt/lib or /usr/local/lib should appear in /etc/ld.so.conf so that ldd can find the shared
libraries. After checking that this is the case, /sbin/ldconfig should be run
while logged in as root.
